背景与目的血液透析对人脑循环的影响，以及血液透析对大脑基底动脉血流速度的影响与若干生理变量之间的相关性研究还不够深入。方法应用经颅多普勒超声检测27例慢性维持性血液透析患者术前、术后即刻大脑中动脉和基底动脉的血流速度。同时记录体重、红细胞压积、血压和动脉血气的变化。结果治疗后大脑中动脉平均血流速度明显降低(P
Background and Purpose The effects of hemodialysis on the cerebral circulation of humans and the correlation between changes in blood flow velocity in the basal cerebral arteries and those of several physiological variables influenced by hemodialysis have been inadequately studied. Methods Blood flow velocities were obtained from the middle cerebral artery and the basilar artery by transcranial Doppler ultrasonography in 27 patients receiving chronic maintenance hemodialysis immediately before and after the procedure. Changes in body weight, hematocrit, blood pressure, and arterial blood gases were recorded simultaneously. Results There was a significant reduction in mean flow velocity in the middle cerebral artery (P
